To aZZ w]: om z't may concern Be it known that I, Hnnnnnr DEAN, a citizen ofthe Dominion ,of Canada, residing at'No. 1&7 Tenth Street- East, in the cityof Brandon, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in an Air- Hose Xipplefor Use in Connection with Air Brakes and Air Signals on Railway Cars, Coaches, Engines,

y-Etc jof which thefollowing is a spec fication. I

This invention relates to improvements in hose nipples which are particularly used on railway trains and an object of theinvention is to provide a nipple which will positively prevent the hose from contacting with any part of the car or engine with which it is associated and which will suspend the hose and coupling at all times clear of the road bed, ties, or tracks, and sufficiently high so that it willnot strike any object lying ,on the road bed.

A furtherobject is to'construct a nipple sot-hat the hose canbe, at all times, easily coupled together andwith little movement of the couplings and which is particularly advantageous in colder countries and insa-ving the hose where the same is sub3ected to freezing.

A further object is to construct a nipple which allows of an adjustment being made in the length of the hose.

A further object is to construct a nipple which can be introduced in the present hose system without having to materially'alter the same.

lVith the above more important objects in view the invention consists essentially in the arrangement and construction of parts hereinafter more particularly described and later pointed out in the appended claims, reference being had to the accompanying drawing in which:

Fig. 1 is a side view of two cars coupled together and fitted with my hose nipples.

Fig. 2 is a plan view of the parts appear-- ing in Fig. 1. v

Fig. 3 is an end view of a car showing the hose coupled together, one of the hose nipples having a portion thereof cut away.

Fig. 4 is a side view of the nipple.

In the drawing like characters of reference indicate corresponding parts the several figures,

ried in pipes located .olnthe undersidelof the cars: and terminating the ends of the ,c ars in angle cocks l. At the present time 7 a short nipple. is, screwed into the angle cock and tothis nipple a comparatively longhose 2 V is attachedythe hose. in reality being approximately twentytwo inches longfand having-the free end thereof carrying the customary coupling 11 91;." i i As, in the above arrangement there is a considerable length of hose and the upper end of the hoseis connected to the angle cock which is at the end of the car,.the hose. which in time becomes quite flexible, can drag on the track when uncoupled or can swrng freely and may become caught around the draft gear rig ging of the foarf This m ght occur when cars, uncouple. and if the hose drags it will become worn or it may become caught in a'frog or snch like and become broken. Qn' the other hand if the hose shouldswing up, and become caught i J dr f gea it l be li more or les's centrally of its length and W111 close the hose and prevent the escape of air, with the result that theair brakes will not be set.

In winter time a long hose, when frozen, 1s apt to crack when bent sufficiently to make the coupling between hoses and difliculty is also experienced owing to the stiffness of the frozen hose and the amount of bend required in making the coupling be tween the hose. I have mentioned the aforegoing disadvantages of'the present hose in order that my invention, shortly described,

and which is extremely simple, may be better appreciated.

Instead of the usual short nipple I substitute an improved nipple, as indicated at 6, Fig. 4, the improved nipple presenting a screw threaded upper end and'having a comparatively long tubular extension 8 which has the lower end thereof angularly bent or deflected, the bend being approximately a twenty-five degree one. 'A hexagon head 9 1s provided adyoming the screw threaded end for tightening up the nipple and the lower end thereof is supplied with; a rib 10 fo r t ning the base,

The hose 11, which according to m invention, is approximately half the length of the ordinary hose, that is to say, about eleven inches long, is attached to the lower end of my nipplelby forcing the one end thereof over the rib 10. The lower end of the hose is provided with the customary coupling hook 12 as at present used. As the hose which I employ is coi'nparatively short it is consequently more rigid and as the nipple which I provide has the lower end bent, the hose normally extends angularly inwardly and downwardly but is supported well clea ot' the track at all times. Further, the hose is ot'such a length and it is supported sutfieiently far enough away from the car that it cannot possibly get caught on the draft rigging. In this connection I might remark that it is the coupling hook at the end of the hose which catches on the draft rigging. Further, the hose to be coupled together are extending towards one another in the uncoupled position and very little bending of the hose is required to make the coupling. This allows of the easier and quicker coupling of the hose and also avoids damage to the hose should the same be frozen. One can shorten the hose, it occasion requires, by sliding the end thereof farther over the nipple. 1

The various benefits above pointed out are dlirectly due to the extension of the nipple and the angular bend given the end thereof, and whilst this is apparently a very simple improvement, it is none the less important as will be obvious by comparing the disadvantages or the present nipple and hose as hereinbe'fore outlined with the advantages gained where my type is employed.

lVhat I claim as my invention is:

1. The combination with the angle cocks of the air pipes of adjoining train sections, of similar nipples screw threaded to the angle cocks and presenting rigid hollow ex' tensions extending angularly downwardly and outwardly from the angle cocks and having-their lower ends angularly deflected further nit vardly towards one another and short flexible hose attached to the angularly deflected ends of the extensions and adapted to be detachably coupled one to the other.

2. The combination with the angle cock of a train air pipe line, of a nipple screw threaded to the angle cock and en'ibodying an elongated rigid tubular extension having the lower end thereof angularly deflected outwardly and a short length flexible hose attached to said angularly deflected end.

3. The combination with the air pipe line of a train section, an angle coc; at one end thereof and a coupling hook at the other end of an air connection between tnc coupling hook and the angle cock con'qn'ising a nipple connected to the angle cock and 0111- bodying arigid tubular extension l'iaving an angularly deflected end and a flexible hose connecting the deflected end of the nipple with the coupling hook, the said hose and nipple being substantially equal length.

l. The combination wi'tn the air pipe of a train section and an angle cock at the end ot the pipe, of a nipple screw threaded to the angle cock and embodying an clong ted rigid tubular extension extending angunxly outwardly and downwardly and having the lower end of the extension further outwardly deflected.
